Diane Krieger has a beloved, 6-year-old American Eskimo dog name Cotton. The problem: Cotton is a biter -- or as Krieger's husband, a lawyer, reminds her: a lawsuit waiting to happen. When solution after solution failed and options grew fewer, as an alternative to euthanizing the dog, Krieger decided on a dental procedure: A doctor would cut away 4 millimeters of Cotton's sharp canines using a laser and then use human-grade composite to give the teeth a smooth, blunt finish.
